4 claims.' (ci. 'zz-44) operation of hollow wall structures built fromspaced cross tied blocks; to provide a hollow wall structure composed ofinner `and outer spaced l blocks in which the'inner and"outer blocks areanchored with relationto each other by cross bars, and all or a portionof the blocks are tied t0 intermediate steel reinforcing bars by weldingor the like: to provide a buildingblock which will form a pair ofparallel spaced walls with a prac-` tically uninterrupted air spacebetween them and co-extensive with the height and length of the walls;to provide a hollow wall structure having within it a reinforcing steelbar frame and in addition thereto sumcient space to receive wiring,conduits, water pipes, etc.; to provide a hollow wall structurelcomposed of spaced inner and outer l:blocks tied with relationto eachother and `intermediate steel bars to form a substantially earthquakeproof structure; and further to provide a hollow wall structure of thecharacter described lwhich may be lthoroughly water and moistureproofed.

'I'heinvntion is shown by way of illustration 30 in the accompanyingdrawing, wherein 4 Fig. 1 is a perspective view of one 'of the wallblocks;

Fig. 2 is aplan view of a partially 'constructed y wall showing themanner in which the horizontal and vertical reinforcing rods are placedin the hollow wall space;

Fig. 3 is a sideelevation of a wall under erection;

Fig. 4 is a cross section of a foundation wall; 40

and Fig. 5 is a plan view of a corner block and an adjacent wall block.

` Referring to the drawing in detail and particularly lto Fig. 1, Aindicates in general the 45.

type of building block employed for wally and foundation structures; Theblock consists of inner and outer blocks indicated at 2 and 3respectively, formed from concrete or any other suitable material. Inthe casting of the blocks 50 they are spaced apart and are permanentlytied q together by metallic members in the form of cross bars 4,beadedat the ends as indicated at 4a so .coated with any suitable material toprevent corrosion, and when reinforcing bars are Vwelded thereto as willhereinafter appear, redlead or a similar coating material should beapplied.

The blocks when placed in a wall will be set up. A

in mortar in the usual way and should be stagv gered to break jointsbetween courses. The cross or tie bars 4 connecting the inner and outerblocks must align vertically when theblocksare built into -a wall. thisbeing important as vertically positioned reinforcing steel rods 4 areplacedv in the 'hollow space formed between the blocks' and are weldedthereto. 'Ihe cross bars 4 will also align horizontally and this isimportant as one or` more reinforcing steel bars 1 are placed on thecross bars'in a horizontal plane and welded either Ato the cross bars 4or to the vertical bars or to. both. The number of vertical andhorizontal bars -8 and 'l employed will depend entirely upon the.

final strength desired. Iiorl instances, thever- A .tical bars may beplaced to engage every .second row of vertically aligning cross bars 4,as shown in Fig. 3, thereby'forming a connection or tie with each block;again, the vertical rods may engage each fourth row of cross rods. Thesame is true of the horizontal bars l, as these may be placed betweenevery other course of blocks or Just as far apar-it as conditions maydemand. In other words, every block in a wall may be tied` or welded toan intermediate steel bar frame or a certain percentage of them maybe soJoined anda substantiallyfearthquake proof structure is thus insured.

To insure vertical and horizontal alignment of the cross bars 4 when theIblocks are set up in 'a wall, let it be assumed that the blocks are 18inches long and 4 inches high. If that is the case, the cross rodsconnecting the inner and outer blocks will be placed on a center line between the upperl and lower faces of the blocks, and 4 inches in fromeach end; by so placing them, vertical' and horizontal alignment is insured, particularly when thelblocks are -stag-v gered between courses tobreak joints.

For the construction of Icorners whereftwo walls meet, corner blocks ofthe type shown in Fig. '5 are employed, and break or staggered jointsare also here insured by mer'ely reversing every otherV corner block..To assist in properly aligning or positioning the blocks in each course,false `rake Joints I0 may be formed in the outer face of each block.This has an addedvadvantage in breaking up the surface, thereby avoidingthel unpleasant I, as to become firmly anchored in the concrete when itsets. The barsl may be galvanized or effect of long rectangular shapedblocks. The blocks may be water and moisture proofed on their inneradjacent faces eitheil before or after placement in a wall. This is alsoimportant as it leaves the main inner and outer faces of a completedwall free to receive any finish or treatment desired.

Sufllee it to sayA that a hollow block wall with an intermediatelyreinforcing steel frame, to which the blocks are tied, is secured; amoisture and water proof structure is insured; the insulating advantagesof an intermediate air space together with space for wiring, piping,etc.. are obtained: and above all, a structureY is provided which can beerected at a minimum cost.

The blocks are intended not only for wall structures but also for solidfoundation walls. When so employed, a footing ii of concrete is firstpoured, on top of which the blocks are placed just as in a wallstructure, two to three or more courses being employed depending uponthe height of the foundation. Vertical and horizontal reinforcing rodsi2 and M- are placed between the blocks and into the footing, and thehollow space is then filled with concrete to make a solid foundation. Afoundation of this character may be employed for ordinary wooden frame.buildings or as a foundation for a reinforced hollow' wall structuresuch as here described. It is cheaper than 'an ordinary foundation asthe lumber and carpenter labor required in connection with the buildingof forms vto receive the concrete is entirely eliminated.

While this and other features of the invention have been more or lessspecifically described and 3. In a hollow wall structure of thecharacter' described, pairs of opposed wall forming blocks, cross barsembedded in and connectingeach pair of blocks, said pairs of blocksbeing spaced apart to form a hollow wall space, said cross rods aligningvertically and horizontally in the wall, and a plurality of verticallyand horizontally disposed steel bars disposed within the wall space andwelded to the cross bars to form a rigidy framework.
